""Double time"" fan system? Dumb?

post #1 of 5
Thread Starter 
I have a NZXT Gamma Case with 6 120mm fan ports, the theory is, can I put 2x 120s on each port*(one inside, one outside)* and using a 12fan controller get better airflow?

then just 6x??

Will they conflict each other?

Should the 2000RPM just be enough to force synchronize

Putting fans in push pull doesnt increase airflow

It offers no performance and just increases noise.

Damn you and your avatar...confused me for a second!


Yeah, it's been shown that putting fans in close proximity to each other doesn't help.

We know that two fans next to each other interact and reduce the airflow. I've tried that myself. Certainly in the front of the case it would be a problem.

That said, I've never tried a fan sandwich with a grill in the middle. That might negate the fan-fan interference.

On the gripping hand, the reason we have push-pull configs on rads and heatsinks is because they tend to have airflow resistance - sometimes a lot. A grill resists airflow, but not a lot for a fan right on the grill. So adding a second fan in theory would at most simply bring the airflow up to something approximating the fans' outputs, but not more - certainly not a doubling of output.

I'll have to go experiment with a fan sandwich sometime. Sounds like fun.
